[webkit-dev] ［GTK］Scroll deficiency

[Brent Fulgham]

I wonder if your issue is related to one I documented on Windows  
(using Cairo backend) a few months ago.  Currently this only happens  
for me in Release builds, but it's still quite annoying.

https://bugs.webkit.org/show_bug.cgi?id=22891

I attached a few images in my bug for comparison.

The easiest way to reproduce is to go to the http://planet.webkit.org  
and try to scroll up/down the page using the scroll bar.  After a  
short while you will find areas of the page not rendered.

Thanks,

-Brent
